Working as root on a Unix/Linux system is <e>dangerous</e> and should be avoided |
| 27 |
swift |

as much as possible. Therefore it is <e>strongly</e> recommended to add a user |

for day-to-day use. |

Now that you've finished installing Gentoo and rebooted, if everything has gone |
| 117 |
|
|
well, you can remove the downloaded stage3 tarball and Portage snapshot from |
| 118 |
|
|
your hard disk. Remember that they were downloaded to your root (<path>/</path>) |
| 119 |
|
|
directory. |
